The instructions were easy enough to follow, but I am wondering about the rate of aeration.* The kit recommends aerating for 10 to 15 minutes. I arrayed for 15 minutes and added 0.4ml indicating 6.4ppm

Seemed lower than it should, so I aerated for another 15 minutes.* Added 0.6ml more for a total of 1.0ml NaOH.* Indicating 16 ppm.

I aerated one more time.* The color change from heat back to pink was slower so this time went for 30 minutes.* Then added 0.4ml more for a total of 1.4ml NaOH.* Indicating*22.4 ppm.

So the aeration time affects the result.* Or do I not have enough air flow for the bubbles?

Can one aerate too long?
